The minimum energy required to launch a satellite of mass \(m\) from the surface of earth of mass \(M\) and radius \(R\) in a circular orbit at an altitude of \(2R\) from the surface of the earth is:
(1). \(\displaystyle \frac{5GmM}{6R}\)
(2). \(\displaystyle \frac{2GmM}{3R}\)
(3). \(\displaystyle \frac{GmM}{2R}\)
(4). \(\displaystyle \frac{GmM}{3R}\)
